The roof hangers may also be fitted
to the rail and motor head if you
know the roof joist positions. Apply
a finger of grease to the chain.
Turn the rail over (chain down) and fit the
rail over the motor shaft and olive. It will
need a bit of patience to align it. Fit two
saddle clamps with the four self tappers.
Place the motor head in its polystyrene
box for protection while assembling.
Find the olive in the accessories bag.
Fit it to the motor shaft first.
Check that the chain engages properly with
both cog wheels. The chain should be long
enough. Slacken off the spring if necessary
When the sections are joined together,
turn the rail over, then turn up all the
remaining locking tabs.
Be careful not to let the chain fall out
when it is upside down.
Tighten the chain checking for tension.
The chain should move sideways, but
not touch the top or bottom of the rail
